COWL OR DRAFT ACCELERATOR FOR STEAMERS.

Specification forming part of Letters Patent No. 16,010, dated November 4, 1856; Ressued May 26, 1857, No. 465.

To all ywhom t may concern.'

Be it known that I, PETER C. GUION, of the city of Cincinnati, in the county of Hamilton, State of Ohio, have invented a new and useful Improvement for the Acceleration of Draft for Flues and Chimneys of Locomotive-Engines and Steamers; and I do hereby declare that the following is an exact description-to wit.

The nature of my invention consists of a conical tube (A) Figure 1, with the forward end the largest, tapering to about onefourth the diameter at the small end, which is inserted in a horizontal flue (C) Fig. 2 and above the perpendicular chimney or flue (D) which is connected with the horizontal flue curving to the smaller end of the conical tube, when the locomotive or steamer is stationary the smoke from the perpendicular flue passes around the conical tube and out of the opening above (E). On the conical tube is fastened a jacket (B) Fig. l so that when the conical tube is inserted in the horizontal flue the acket slips over the upper flue, when the locomotive or steamer is in forward mot-ion, thereby letting a draft of air pass direct-ly through the tube and through the Hue over the locomotive and cars or over the steamer to the stern part of the vessel. This circulation of air as it passes out of the smaller end of the conical tube in the horizontal flue produces asuction and strong draft in the lower upright chimney which accelerates the draft thereby causing th-e fuel to burn briskly and insures a strong and steady .draft through the furnace generating more steam with a given quantity of fuel and consuming most of the smoke. The valves Figs. 3 and l are fastened to an arm (Gr) connected with a lever (P) which moves the valve in position, the main valve H has a slot to pass over the conical tube and on the slot is a small valve (L) which when the main valve is raised up falls over the slot and is raised with the main valve in shutting the upper opening; there is a support (K) to secure the small end of conical tube in place and when the main valve (H) is let down it falls over and around the conical tube and support- (K) thereby opening the upper mouth or top of chimney and closing the horizontal tube letting the smoke pass upward when the locomotive is stationary or moving backward.

Fig. 5, is a vertical position of conical tube (A) with cross partition (N) extending in the large end and about one third the length of tube (A) the partitions form separate air ducts which open into the conical tube (A) at the termination of the partition (N) the base or cone (J) is fastened to the roof of the boat or house, on the sides of cone (J) are fastened the partit-ion (N) extending up and fastened to flange (M) which form the opening for receiving air from any direction. Flange (M) is a flat rim lying in the partition (N) and fastened to conical tube (A) the conical tube A, is inserted into the upright chimney at the stern of the boat, this application of the accelerator in a vertical position at the after part of the chimney secures a strong draft when the wind is blowing in the same direction the boat is running, and adds additional draft when the wind is blowing in any other direction by receiving air in both the horizontal and vertical accelerator at the same time.

Fig. 6 represents cone (J) with the partitions on with the conical tube off.

I do not claim any of the several devices, surfaces or parts described separately but I do claim- Their combination constructively in the manner and for the purposes hereinbefore described and shown.
